I’m not sure why numbers are filled in, when I only solved one segment. Is there a way to turn that off?

★★★★★ I've used this app for years, and it's an amazing sudoku app that works well and has a nice scoring system and helpful tips and strategies. Recently, however, they updated the app to where you can only play a certain…

★★★★★ Not a bad app until it forces you to wait almost 3 minutes when you start the app or when you complete a sudoku you have to wait 3 minutes. That is really the tipping point for me. It's forcing you to pay for the app…

★★★★★ Friend battle is STILL not working.
★★★★★ I really like this Sudoku game, but sometimes when I switch to another app in my phone and then go back to the game, I find that it exited me from my puzzle and I have to start a new one. It doesn't happen all the…
★★★★★ The “Friend Battle” option doesn't do a single thing whatsoever. What's the point of that function if it does absolutely nothing?

★★★★★ Der Timer zwischen den Spielen macht es leider kaputt… davor habe ich sehr gern gespielt
★★★★★ Recently, however, they updated the app to where you can only play a certain amount before having to wait for a cooldown.
★★★★★ But after I updated, you have to wait a certain amount of time to start a new game.

★★★★★ So there was no way to complete the puzzle & no way to report the issue.
★★★★★ It lacks the option in settings to remove help to solve.
★★★★★ Now unusable because there is no way to remove candidates

★★★★★ it will tell you your number position is correct and then when you get to the last few numbers you realize they're all wrong… what's the point of misleading?
★★★★★ The other annoying features such as noise, vibration, timer, can be turned off, but when you enter a number, the app populates additional squares, making it useless.
★★★★★ first game i played i asked for a hint and the hint was incorrect, accuracy in games like these are essential.

★★★★★ I originally loaded this game because it was free and have enjoyed it for a while but now they want to limit play unless you pay.

I’m not sure why numbers are filled in, when I only solved one segment. Is there a way to turn that off?
Love this app!! Very grateful for no ads and I love the technique videos. However, it would be nice to have a feature that allows me to move the numbers from the right side of the screen to the left. I play on my iPad and as a left handed person it gets a little annoying always reaching across the sudoku pressing numbers. I would really appreciate a feature like this!!
it will tell you your number position is correct and then when you get to the last few numbers you realize they’re all wrong… what’s the point of misleading?
I loved this app and played frequently until they changed the layout, and the new look is distracting and I not conducive to a puzzle
Friend battle is STILL not working. We both have the annual subscription and are unable to successfully play friend battle. Please fix this, as it is currently a huge waste of money.
